Refactor Parser to make it usable on a background thread.

- Background Parsers cannot get the following data from Isolate (pass it to the
ctor instead): stack limit (background Parsers need a different stack limit),
UnicodeCache (background parsers need a separate UnicodeCache), hash seed
(Parser cannot access the Heap to get it). The Parser::Parse API won't change.

- Make the internalization phase (where Parser interacts with the heap) more
explicit. Previously, Parser was interacting with the heap here and there.

- Move HandleSourceURLComments out of DoParseProgram, so that background parsing
can use DoParseProgram too.

More aggressive reuse of spill slots in the register allocator.

Two improvements:
- At phi nodes, we now try to merge operands into one spill slot and
then reuse the spill slot for the phi.
- After register allocation we merge disjoint spill slots.

With this change, I see about 4% improvement in zlib.

MIPS: Refactoring InterfaceDescriptors away from code-stubs.h - external.

Port r23515 (fe0bdbf)

Original commit message:
Clean up and create seperation between the concept of a call descriptor and a
code stub interface descriptor. The former is just concerned with how to call,
but the latter has many extra hints related to code generation and
deoptimization for the implementation of a particular code stub.
